I know this post is from awhile back Gary. But a funny thing happened when we took the steel ballast box for sand blasting and coating. I was planning to coat with zinc paint (like a cold galvanising) and the boss told me that was old hat. For the Gorgon gas platform and Alcoa port facilities they use a polymide coating, DTM985. They pile drive poles with that coating through rock. He showed me a coated pipe and challenged me to scratch it off with my keys. Could only scratch the shiny surface, the rest was rock hard. They just spray it on. Maybe it was the same suff your mast head has.
So now we have a glossy black keel, inside and out, sitting in our carport. Shame to anti foul it.
